# setImageData(_:)

Sets the displayed image using a formatted data object.

## Declaration

```swift
func setImageData(_ imageData: Data?)
```

## Parameters

- `imageData`: A data object containing the image data in its native format. Specifying nil removes the existing image, causing the watch interface to display nothing in the space previously occupied by the image.

## Discussion

Discussion This method changes the image being displayed. When setting images, always try to use images that are sized to fit the available space. Images are rendered according to the mode and size attributes you set for the image interface object.
